OOMMINUTING OE GRINDING MACHINE.

Application filed February 18, 1924.

To all whom it may concern:

Be it known that I, ELLIOTT CARNS, a citizen of the United States, residing at South Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Comminuting or Grinding Machines, of which the following is a specification.

This invention relates to a comminuting or grinding machine primarily for food products.

An important aim is to provide a means whereby the discharge end construction of the bowls of existing machines, particularly those having exterior screw threads for attachment of an end ring thereto, will be rendered and kept more sanitary, may be opened and closed easier and rapidly, and the user will be encouraged to more frequently clean the same to thus particularly adapt said existing bowls for application thereto of the improvements disclosed in my Patent 1,498,262, covering an improvement in comminuting or grinding machines, issued June 17, 1924, and toalso adapt said existing bowls for application thereto of improved end ring constructions generally, particularly those rendering operation easier and more rapid and promoting sanitation, to the end that all of the objects and advantages, as well as those otherwise peculiar to the present invention, set forth in the said patent may be realized.

Another object is to provide a construction wherein an adapter collar is used which covers the screw threads of the bowl and which removes foreign matter from such threads incidental to its application thereto, and will prevent entrance of foreign matter between the bowl and collar when the latter is in place.

A further object is to provide a construction wherein the adapter collar has means rigid, preferably integral, therewith and constituting part of separable connecting means for the replacement end ring to reinforce the collar and be capable of use as abutments for the fingers of'the operator when applying the adapter collar to the bowl.

f .Various additional objects and advan: tages will become apparent, some being further pointed out from a con ideration Serial No. 693,613.

of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings:

Figure 1 is a side elevation showing the improvements applied to a bowl;

Figure 2 is an end elevation looking toward the discharge end of the bowl;

Figure 3 is a fragmentary side elevation, partly in section, illustrating details of the end construction of the bowl;

Figure 4 is a front elevation of the adapter collar;

Figure 5 is an edge elevation of the adapter collar and Figure 6 is a vertical sectional. view through the replacement end rin .Referring specifically to the drawing wherein like reference characters designate like or similar parts in the difierent views thereof, bowl A is of conventional construction, consisting primarily of a supply hopper B leading to a barrel or cylinder C whose axis is horizontally disposed. Within cylinder C, a usual feed screw and cutter or the equivalent (not shown) and a perforated plate D are removably disposed. On barrel or cylinder C adjacent the discharge end are exterior screw threads E adapted for threaded engagement as usual by an ordinary end ring (not used or shown).

In place of the ordinary end ring, an

adapter collar 13 is employed which has interior screw threads 14 to removably engage and completely cover those at E. Collar 13 may be a casting with the threads 14 thereof appropriately machined, if desired. Said collar 13 has any suitable number of outwardly radiating lugs 15 usually integral therewith at a distance inwardly of the discharge or end of the barrel where plate D is located, Lugs 15 loosely and detachably carry the shanks of bolts 16 having heads 17 and on which nuts 18, as of the wing type to facilitate linger manipulation are employed. -The adapter collar 1-3 be tween lugs 15 and the remote end thereof has a-truly cylindric surface 19. -Lugs 15 serve as abutments. for the fingers of the operators hand in the acts of applying and removing the adapter collar.

The end ring used as a replacement or ubstitute for the ordinary or disca ded d ring is generally designated 20, and may be identical in construction With that disclosed in my Patent 1,498,262 aforesaid although the construction does and it is an object to accommodate all improved forms of end rings, particularly those designed to render operation easier, more rapid and which increase sanitation. This ring may be a single metallic casting generally of L-shape in cross section so as to have a relatively wide annular wall 21 and an inwardly extending flange .22 at its Outer marginal edge, Adjacent the inner narginaleclge, outwardly extending hooklugs 23 are provided equal in number and spaced similarly. to lugs .15. Said lugs 23, are of. considerably less thickness than the. width of the end ring 20, so that th e heads 17 will as shown in Figure 1 be located a considerable distance inwardly of thetlange or outer end of th e ring in order no t to interfere with manual. engagement or gripping of said ring. Lugs-2 3 have arcuateslotsf 24 to..receive the bblts16 The wall 21 in line with lugs 23. hasexterior depressions 25 which serve'as fingerholds and also enable the b oltsrlfi andilugs 23 to be located closer. to the center of: the

. end ring, 'resnlting in a more cornpactc0n- I may use a suitablenumber of. relatively small teats 26 on cylinder C, for. instance eduidista'nily between and of the same number. as lugs 15.

Various changes may be resorted to provided they fall within thespirit and scope of the invention.
